Targeted for audio equipment and automotive applications, the part offers a wide operating temperature range from −55 °C to +105 °C and meets AEC-Q200 qualification and RoHS requirements for use in demanding environments.

Key Features

• Capacitance & Voltage — 4.7 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance (120 Hz, 20 °C).
• Compact SMD Can — Chip-type SMD can with dimensions L: 4.5 × D: 4 mm and recommended land pattern L: 4.3 × W: 4.3 mm for space-constrained board layouts.
• Wide Temperature Range — Operates from −55 °C to +105 °C, enabling use across extended ambient conditions.
• Automotive Qualification — AEC-Q200 qualified, suitable for automotive electronic designs that require established component-level qualification.
• Endurance at Elevated Temperature — Rated for 1000 hours at 105 °C for the 4.5L configuration, meeting lifecycle expectations for high-temperature use.
• Electrical Performance — Low leakage characteristic (≤ 0.01CV or 3 μA after 2 minutes at 20 °C), tan δ max 0.16 at 25 V (120 Hz, 20 °C), and specified ripple current of 15 mA at 120 Hz and 22.5 mA at 10 kHz.
• Assembly Compatibility — Designed for automatic mounting machines and carrier-tape feed to streamline high-volume PCB assembly.
• Regulatory Compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Chip-type acoustic series construction and datasheet designation “For Audio Use” make this capacitor suitable for audio circuitry in compact assemblies.
• Automotive Electronics — AEC-Q200 qualification supports use in automotive modules that require qualified passive components.
• Automated Surface-Mount Production — Carrier-tape compatible package enables efficient pick-and-place assembly for high-volume manufacturing.
• Space-Constrained Board Designs — Small footprint (4 × 4.5 mm) provides capacitance in tight PCB real estate for board-level designs.

Unique Advantages

• AEC-Q200 Qualified: Provides component-level qualification for applications that require automotive-grade reliability.
• Wide Operating Temperature: −55 °C to +105 °C range allows deployment across harsh and varying thermal environments.
• Compact Form Factor: 4.5 × 4.0 mm can and matching land pattern reduce PCB area while remaining compatible with automated assembly.
• Defined High-Temperature Endurance: 1000-hour rating at 105 °C for the 4.5L size gives predictable lifespan under elevated-temperature stress.
• Measured Electrical Parameters: Specified leakage, tan δ (0.16 max. at 25 V), and ripple current values support predictable performance in design calculations.
• RoHS Compliant: Meets current RoHS directives for environmentally restricted substances.
